Replace instances of svn_stringbuf_ncreate() that create an empty stringbuf.

* subversion/libsvn_subr/subst.c

(keyword_printf): Use svn_stringbuf_create_empty where appropriate.

* subversion/mod_dav_svn/deadprops.c

(db_open): Same.

* subversion/tests/libsvn_subr/skel-test.c

(get_empty_string): Same. The original code is even illegal.

Make the C tests work with the --enable-optimize configure option.

Because the main() function used to be defined in libsvn_test,

the -flto option (which performs rather aggressive link-time

optimizations) would cause the linker to remove all "unreferenced"

static functions ... which includes all the actual tests.

Which this change, main() is now defined in each test driver.

* subversion/tests/svn_test.h

(test_funcs, svn_test_max_threads): Remove external declarations.

(svn_test_main): New prototype for the (existing-but-renamed) test driver.

(SVN_TEST_MAIN): Bolierplate macro that generates a main() implementation.

* subversion/tests/svn_test_main.c

(svn_test_main): Renamed from 'main', and takes two extra parameters,

'max_threads' and 'test_funcs'. Propagates test_funcs to get_array_size,

do_test_num and do_tests_concurrently.

(get_array_size, do_test_num,

test_params_t, test_thread, do_tests_concurrently): Require a test_funcs

parameter. All uses updated.

Add "--parallel" option to our C tests.

Besides shaving off a few seconds off our total test execution time,

parallel execution also stresses our code and the tests themselves

harder. It uncovers things like improperly separated working sets

that make post-failure analysis harder.

Parallel mode is only available with APR 1.3+ and threads enabled.

The option will simply be ignored in other configurations. Further

limitations are cleanups being delayed to after all tests completed

and segfaults not being intercepted.

Some tests can't be executed in parallel. Therefore, we introduce

svn_test_max_threads a simple upper limit to the number of threads

supported that each test must define alongside the test_funcs array.

This patch sets it to "1" in many cases because the tests are so

small that multi-threaded execution is simply not worth it.

* build/run_tests.py

(TestHarness._run_c_test): Pass --parallel option to the individual

test applications.

* subversion/tests/svn_test.h

(svn_test_max_threads): Declare new external setting to be set by

every test application.

* subversion/tests/svn_test_main.c

(parallel): New command line option presence flag.

(parallel_opt,

cl_options): Declare the new "--parallel" option.

(svn_test_add_dir_cleanup): Synchronize shared pool access since

this might be called from multiple

threads at the same time.

(log_results): Result logger function factored out from do_test_num

to be shared between serialized and parallel test

execution code.

(do_test_num): Use that new function.

(test_params_t,

test_thread,

do_tests_concurrently): Threads, their parameter and the thread

starter for thread-pooled test execution.

(main): Handle the new option.

Call concurrent execution when in PARALLEL mode.

Merge r985037, r985046, r995507 and r995603 from the performance branch.

These changes introduce the svn_stringbuf_appendbyte() function, which has

significantly less overhead than svn_stringbuf_appendbytes(), and can be

used in a number of places within our codebase.

r995507 is the removal of an extra function on the branch. This function

conflicted with previous revisions in the merge, and is itself no longer on

trunk.

Replace deprecated test func macros in the C tests. This eliminates the need

to do the following dance in every test function:

*msg = "foo";

if (msg_only)

return SVN_NO_ERROR;

This does not remove the deprecated symbols from svn_test.h; I plan to do it

in a follow up commit.

dictates we make this change.
